Objective: To assess the complication rates and quality of life in patients eligible for focal therapy who underwent template-assisted transperineal prostate biopsy (TTPB).
Materials And Methods: Eighty-seven patients with low-risk prostate cancer (clinical stage T1c-T2a, prostate-specific antigen level ≤10 ng/mL, biopsy Gleason score ≤6), who were candidates for focal therapy, underwent TTPB. The study details are available from http://clinicaltrials.gov (NCT00928603). The primary outcomes were the complication rates, according to the Clavien-Dindo classification, and changes in the quality of life, evaluated using the International Prostate Symptom Score, International Index of Erectile Function, and Functional Assessment of Cancer Therapy-Prostate questionnaires, before and 1 month after TTPB.
Results: The median patient age was 63.9 years (range 46-78), with a median Charlson comorbidity index of 2.2 (range 0-4). No statistically significant differences were observed when comparing the general and/or specific domains of the International Prostate Symptom Score, International Index of Erectile Function, and Functional Assessment of Cancer Therapy-Prostate results before and 1 month after TTPB (P >.05 for all). Using the Clavien-Dindo classification, we observed 37 cases of grade 1 complications, including 5 (6.1%) cases of macrohematuria, 13 (16%) of hemospermia, 11 (13.5%) of perineal hematoma, 3 (3.7%) of perineal hematoma and hemospermia, and 5 (6.1%) of macrohematuria and hemospermia. Three patients (3.7%) developed a grade II complication (ie, acute urinary retention). Prostate cancer was detected in 54 patients (62.1%). Of 57 patients, 16 (29.6%) were upgraded from Gleason score 3+3/atypical small acinar proliferation to Gleason score 7. Of the 54 patients with positive TTPB findings, 18 (25.3%) showed an anatomic correspondence between the results of previous biopsies and TTPB.
Conclusion: TTPB did not appear to have a significant effect on the quality of life of candidates for focal therapy, and the Clavien-Dindo complication rate was negligible.

Background: Cancer pain is a prevalent and persistent issue, and while there have been some observations of the possible benefits of acupuncture in managing cancer pain, there is still debate regarding its safety and effectiveness. This study aims to compare the efficacy and safety of different acupuncture modalities in the treatment of cancer pain through a network meta-analysis.
Methods: Between the time each database was created and June 3, 2024, eight databases were queried: PubMed, Cochrane, Embase, Web of Science, CNKI, Wanfang, VIP, and China Biomedicine.
Secondary amputation: a qualitative study of quality of life in patients after primary limb salvage surgery and after later ablative sarcoma treatment.

Objective: This study focuses on how patients experience the time following amputation after primary limb salvage surgery due to musculoskeletal malignancies. Limb salvage is state of the art in the treatment of musculoskeletal tumours. Nonetheless, in some cases, limb salvage can become problematic over time, resulting in poorer limb function and septic outcomes.

The study investigated this in the context of assisting with daily activities. The quality of the relationship was assessed using the conceptual framework of relationship continuity/discontinuity which focuses on whether the carer experiences their relationship as continuous or discontinuous with the pre-dementia relationship.

Gout is a commonly occurring form of inflammatory arthritis caused by persistently elevated levels of uric acid. Its incidence rate rises with the increases of living standards and poor dietary habits, which has a considerable impact on the quality of life of the patients. Although there is a wide assortment of drugs available for the management of gout, the effectiveness and security of these drugs are limited by their poor chemical stability and insufficient targeting.
